A.J. Pollock will have surgery on his fractured right hand in the next few days and Arizona manager Kirk Gibson expects the young outfielder to be sidelined approximately five to eight weeks.
Gibson, speaking before Sunday's game against Cincinnati, said that timetable was just a guess.
The Diamondbacks placed Pollock on the 15-day disabled list and purchased the contract of outfielder David Peralta from Double-A Mobile. Peralta was in the Arizona lineup in left field for Sunday's game.
Pollock was hit in the hand by the Reds' Johnny Cueto in the eighth inning of Saturday night's 5-0 loss to Cincinnati.
He had been one of the team's best players over the past month, batting .344 since April 4.
